About Game Score & Impact
Ohio Sports Brief evaluates every MLB performance with two proprietary metrics designed to capture both quality and influence on the game.
GS
Game Score
Game Score is a single-number rating of how well a batter or pitcher performed in a game. It blends the most meaningful parts of a box score — contact quality, run production, plate discipline, damage allowed or prevented, and workload — into one balanced index.
Higher is better. A strong Game Score means a player did the things that typically help a team win: hitters created runs and avoided unproductive outs; pitchers worked deep, limited baserunners, and kept runs off the board.
Team Game Scores on our reports combine all of a club's batting or pitching lines into one team total, then evaluate that combined performance as a unit — giving you a fair read on how the whole offense or staff performed, not just a headcount of individual standout lines.
IM
Impact
Impact measures how much a player's performance actually moved the needle in that game. Where Game Score reflects how well someone played, Impact reflects how much it mattered given the volume and context of their contribution.
A reliever who threw one perfect inning and a starter who carried a complete game can both post strong Game Scores — but their Impact numbers will differ based on how much they were involved and what they prevented or produced over their time on the field.
Team Impact totals sum each player's Impact across the roster. That makes it useful for spotting which side had more players who not only played well, but played well at meaningful volume.
How to read a game report
- Matchup board — final score with team logos, Game Score and Impact bar charts, and Player of the Game.
- Side-by-side tables — every batter and pitcher in the game, ranked by individual Game Score.
- Team totals — Game Score is computed from combined team stats; Impact is the sum of individual player Impact values.
The exact weighting behind Game Score and Impact is proprietary. The metrics are built to reward complete, winning baseball — not any single counting stat in isolation.
